The Mommy Megaphone is a gag gift for parents that bills itself as a "sure-fire way to get everyone to listen." It has a speak mode and a siren mode, can project over 500 feet and is allegedly weather and baby-resistant. With an adjustable volume range of 5 to 10 Watts however, it's almost completely useless. Kids are yelly; when I was young, I'm pretty sure I'd hit 10 Watts in a normal conversation. You know what would be more effective? Holding up a paddle. That always got me to listen right quick.
